Gregory Alan "Greg" Maddux (born April 14, 1966 in San Angelo, Texas) is a former Major League Baseball pitcher. He was the first of the only two pitchers in major league history to win the Cy Young Award for four consecutive years (1992-1995), the other being Randy Johnson (1999-2002). Maddux had a 75-29 record with a 1.98 ERA, while allowing less than one runner per inning, during 1992-1995.

Maddux is the only pitcher in MLB history to win at least 15 games in 17 consecutive seasons. In addition, he has been awarded a record eighteen Gold Gloves. A superb control pitcher, Maddux won more games during the 1990s than any other pitcher, and is 8th on the career wins list, with 355. Only Warren Spahn (363) has more career wins among pitchers whose entire careers were in the post-1920 live-ball era.

Maddux was born in San Angelo, Texas, but spent much of his childhood in Madrid, Spain, where the United States Air Force had stationed his father. His father exposed him to baseball at a rather young age, and kindled his passion for the sport. Upon his return to Las Vegas, Nevada, Maddux and his brother Mike trained under the supervision of Rusty Medar, a former scout from the majors. Medar preached the value of movement and location above velocity, and advised throwing softer when in a jam instead of harder; Maddux would later say, "I believed it. I don't know why. I just did." Though Medar died before Maddux graduated from Valley High School in Las Vegas, he instilled a firm foundation that would anchor Maddux’s future career. Maddux currently lives in the same community.
